Question

Quizplus · Accepted Answer

Bird and bat wings are analogous as structures because they serve similar functions (flight) but are not derived from a common ancestral wing structure, making them homoplastic. However, they also have homologous components, such as the bones in their wings, which are derived from common ancestral forelimbs, thus sharing an evolutionary origin.
